The Lyman-..cap alpha.. polarization fractions resulting from e/sup -/-H(1s) collision are calculated within the conventional Glauber and modified Glauber methods, in which the Glauber exchange effects are no longer neglected. It is found that in the conventional Glauber case, the inclusion of exchange effect completely changes the shape of the theoretical result curve at energies below 30 eV in comparison to the one obtained in the previous calculation without exchange and, furthermore, worsens somewhat the agreement with experimental data at energies between 30 and 60 eV. The new theoretical values obtained with the modified Glauber method with exchange are found to improve significantly the agreement with experimental data at intermediate scattering energies. However, the modified method still fails to account for experimental data below 30 eV, as expected.
